BACKGROUND

1. Technical Field

The present invention relates to the field of data modeling. Particularly, the present invention relates to automatic generation of business decision analytic models.

2. Description of the Related Art

The task of model generation, especially generation of models which are business centric and involved business decision making, is a task that depends on availability and scrutiny of large volume of information. The process of model generation has always been an information centric process which dwells on the availability of quality information corresponding to the problem domain the analytic model expected to cater to.

However, given the exponential increase in the amount/volume of data available with respect to any particular problem domain, the task of choosing the right set of data/variables for model generation becomes a cumbersome task. Wide spread use of the internet and collaboration and consumer platforms like social media and online shopping are resulting in enormous amount of data being generated via blogs, social interactions, product reviews etc. In addition, the machines being used in the process (computers, smart phones, network equipment and the like) are also contributing to the data growth.

The availability of larger volumes of data has resulted in a situation where selecting an appropriate set of variables for model creation becomes a cumbersome task. Further, until recently analytic model generation was carried out manually. The process of manual generation of analytic/predictive models was a complicated task by itself and required huge investments in terms of time-frames and man power. Moreover, human decisions and judgments in terms of variable selection for model generation are prone to errors which could in turn compromise the efficiency and effectiveness of the generated analytic models.

Therefore, there was felt a need for a system which obviated manual intervention and automated the entire process of model generation. Moreover, another challenge in the arena of model generation was to generate a model that is adaptable and flexible enough to incorporate the changes in the data inflow. Therefore, there was felt a need for system that not only automated the generation of analytic models, especially business critical analytic models but also converts unstructured data into structured information before using the same in the process of model generation. There was also felt a need for a system which puts in to use the phenomenon of automation in order to bring down the time associated with model creation and model updating. There was also felt a need for a system that is capable of automatically regenerating a previously created analytic model based on the inflow of newer data.

The above mentioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.

OBJECTS

DETAILED DESCRIPTION OF THE DRAWINGS

In the following detailed description, a reference is made to the accompanying drawings that form a part hereof, and in which the specific embodiments that may be practiced is shown by way of illustration. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that the logical, mechanical and other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense.

The present invention envisages a computer implemented system and method for automating the generation of an analytic model, typically a business decision analytic model. The system and method envisaged by the present invention proposes breaking down the steps involved in model generation and provides for rapid building, utilization and automated maintenance of the analytic model. The system and method envisaged by the present invention automates the process of analytic model building by utilizing specifically designed software tools, thereby reducing the build time and use time associated with analytic models. In addition, the present invention also provides for quality enhancement of the crated analytic models by enabling automatic model selection and automatic model regeneration.

Referring to FIG. 1, the computer implemented system 100 for automating the generation of an analytic model is shown. The system 100, in accordance with the present invention comprises a repository 10 configured to store a plurality of data sets. The data sets stored in the repository comprise predictor variables which are to be utilized for generating the analytic model. The system 100 further includes a processor 12 configured to process the predictor variables and generate an analytic model.

In accordance with the present invention, the processor 12 comprises a determinator 12A configured to determine the total number of records present in each of the data sets stored in the repository 10. The determinator 12A is further configured to identify the columns of the data sets containing only numerical values. Further, the columns of the datasets containing only numerical values are forwarded to a selector 12B. The selector 12B selects a column containing only numerical values (numeric column) from one particular data set (data set under consideration) at a time. The selector 12B further comprises a counter 121 configured to count the number of unique values in the selected column. Further the counter 121 counts the number of total records present in the selected column.

In accordance with the present invention, the system 100 further includes a comparator 12C configured to compare the total number of unique values in the selected column with the total number records in the selected column. The comparator 12C compares the number of numeric columns with the total number unique values so as to determine/identify the exact number of columns around which the data is clustered. The number of unique values in the selected column being less than the total number of records in the selected column indicates that the data is clustered around a small group of values, and transformation of such a column and utilization of the same in model generation would be relatively non-cumbersome task. If a particular dataset is clustered around a few unique numerical values, computing a nonlinear transformation such as obtaining the logarithm of the variables would act as a value addition to the quality of the model, and improves the overall quality of analytic models since not only the variables but their respective logarithmic values are also being utilized for the purpose of model generation. The comparator 12C, based on the output of the comparison, selectively transmits the selected column to the transformation module 14.

In accordance with the present invention, the transformation module 14 transforms the column transmitted by the comparator 12C by applying a non-linear transformation to each of the values in the selected column. Further, the transformation module replaces the original numeric values present in each of the cells of the column with the respective transformed values.

In accordance with the present invention, the system 100 further includes a time stamping module denoted by the reference numeral 16. The time stamping module accesses the columns transformed by the transformation module 14 and determines if there exists any timestamp denoting the date and time on which the data in the cells were created. The time stamping module 16, unlike the comparator module 12C takes into consideration a row of the data set (under consideration) and determines whether the row of data has been time stamped.

In the event that a row of data in the data set under consideration has been time stamped, the time stamping module creates time lags corresponding to each row of data. For example, the time stamping module 16 considers the time elapsed between n^(th) row of data and the (n+1)^(th) row as the first order time lag of data arrival, and associates this time lag with (n+1)^(th) row. Similarly the time stamping module 16 calculates the first order time lags for all the available rows of data. Further, the second order time lag for all the data rows is calculated by considering the time elapsed between n^(th) row of data and the (n+1)^(th) row of data, and associates the calculated second order time lag with the (n+1)^(th) row. In case of availability of time stamps for the row of data under consideration, the time stamping module 16 creates time-lagged variables of pre-determined degrees (first degree and second degree) and evaluates the importance of the time-lagged variables in terms of their contribution to the model quality, and automatically chooses the optimal time lag (either the first order lag or the second order lag). In case of availability of time stamps, the time stamping module 16 also computes variables that indicating how time impacts the observations. An example is the elapsed time for a variable to move from one value to another. The time stamping module 16 computes a library of such variables and provides for automatic evaluation of their utility.

The system 100, in accordance with the present invention further includes a creator 18 configured to create a processed data set. The processed data set comprises transformed values arranged in a tabular format, i.e., in terms of rows and columns. The creator 18 cooperates with a model generator 20 which makes use of the processed data set and creates an analytic model (also referred to as the baseline model) using the processed data set.

In accordance with another aspect of the present invention, the system 100 further includes a model testing module 22 having access to a module quality evaluation metric. The model testing module 22 tests the analytic model developed by the model generator 20. The model testing module comprises 22 a splitter 22A having access to the processed data set used for creating the analytic model. The splitter 22A splits the processed data set into typically a first set and a second set, in accordance with a pre-determined criterion. For example, if the split criterion is 2:1, ⅔^(rd) of the earliest data is selected as the model development data and ⅓^(rd) of the later data is selected as the test data. However, it is within the scope of the present invention that the processed data set can be split into more than two sets. In accordance with another aspect of the present invention, 70% of the processed data set is considered as the model development data and the rest (30%) is considered as the model test data.

The testing module 22 further comprises a second selector 22B which select at least one data item for omission from the first set and the second set and creates a new first set and new second set omitting the selected data items. Several factors are taken into consideration by the testing module 22 for selecting a variable for omission. For example, a variable having the lowest information gain against the predicted variable can be dropped, a variable that has the lowest variability is the first one to be dropped and a variable that has missing data can be dropped.

The creation of new first set and the second set provides a base case to evaluate how an analytic model that does not include a particular variable would perform. The second creator 22B transmits the new first set and new second set to the model generator 20 for the creation of a second analytic model.

The model testing module 22 further includes a second comparator 22D which compares the analytic model (baseline model) with the second analytic model and determines whether the quality of the second analytic model is better than the baseline model. The second comparator 22D is further configured to eliminate the data item (which was selected for exclusion) from the new first set and second set in the event that the quality of new analytic model is not inferior to the quality of the baseline model. In the event that the quality of the new analytic model is inferior to the quality of the baseline model, then the data item, initially selected for exclusion would be retained. In this manner an analytic model created by the system 100 is iteratively tested and the quality of the model is improvised upon.

In accordance with the present invention, the splitter 22A is configured to split the processed data set into first data set and second set in a chronological order, wherein the chronological order identifies the order in which each of the rows of the processed dataset were previously created. Further, the splitter 22A can also split the processed data set into first set and second set in a pre-specified order, in the event that no chronological order data is available. In such a case, the splitter 22A randomly shuffles the data items of the processed data set prior to splitting the data set.

In accordance with the present invention, the system further includes a model updating module 24. The model updating module 24 is configured to update the analytic model, typically the baseline model, in a stateful manner. Stateful model updating is invoked for those model forms where this method can be used. For example, linear regression model can be incrementally built such that only the new data needs to be presented to the model generation along with a minimal state information from the time this model was generated the last time.

The model updating module 24 is also configured to update the analytic model in a stateless manner. Stateless model updating is computationally more expensive. It is done where the underlying analytic model form does not yield itself to the less expensive stateful model updating. For example, a neural network model does not lend itself to an incremental updating where the current model that was built on historical data is relearnt with the new data. In such cases, the current model is discarded and the model is fully learnt using the full data that includes as much data as necessary and will include historical data and current data.

For example, consider a model that is generated using data that was generated over a time window indicated by [T1, T2] where T1 is the data start time and T2 is the data end time. After some time has elapsed, new data becomes available over the time window [T2+1, T3]. An analytic model that is amenable to stateful update, is updated/regenerated by the model updating module 24 using just the new [T2+1, T3] data without it discarding what has been modeled over [T1, T2]. An analytic model that is not amenable to stateful update will be updated/regenerated using just the full [T1, T3] data.

In accordance with another aspect of the present invention, the system 100 further comprises a converter 26 configured to convert unstructured data into structured information and store the structured information in the form of data sets in the repository 10 for the purpose of automation of generation of analytic model. Unstructured data is a term used to describe data that is a mixture of textual and non-textual data. Unstructured non-textual data generally relates to media related data such as images, video and audio files. As the volumes of this type of data increases, the need to analyze and understand it grows too. Slightly easier to analyze and less unwieldy are unstructured textual data made up of different file types (documents, spreadsheets and presentations), email messages, social media postings and an array of other files generated and stored on corporate networks. For example determining the level of satisfaction of customers by analyzing emails and social media postings may involve searching for words or phrases.

The converter 26 comprises a receiving module 26A configured to receive the unstructured data. A filter 26B filters the unstructured data to identify and retrieve a plurality of sections of unstructured data based on the relevance of the unstructured data to the creation of the analytic model. Further, a natural language processing tool 26C receives the sections of unstructured data and breaks the sections of unstructured data into a plurality of meaningful sentences using natural language processing tools. A parser 26D parses the plurality of meaningful sentences and retrieves a plurality of keywords from the meaningful sentences.

The converter 26 is further configured to assign a weight value and a sentiment value to each of the keywords, and categorize said keywords into a plurality of categories based on a pre-determined categorization criteria thereby converting said unstructured data into structured information which is stored in the repository 10 and utilized for creating the analytic model. The converter 26 groups the words and phrases into positive, negative or neutral classifications, thereby transforming the unstructured data into structured data where the groups of words found based upon their classification are assigned a value. A positive word may be assigned a numeric value of 1, a negative may be assigned a numeric value of −1 and a neutral may be assigned a numeric value of 0.

In accordance with the present invention, the system 100 creates a plurality of analytic models for a given problem. The system 100 considers one of the models as the baseline model and the baseline model will be placed in service until it is replaced. All the models, other than the baseline model are in the background—not in production yet but ready to challenge the incumbent model (baseline model). The baseline model is the model that produces the best performance over the test data. On an ongoing basis, as new data flows through the system 100, each model, including the incumbent baseline model, is evaluated against the new data. The model the produces the best performance over the new data becomes the new baseline model replacing the incumbent.

Referring to FIG. 2, there is shown a computer implemented method for automating the generation of an analytic model. The method, in accordance with the present invention comprises the following computer implemented steps: storing, in a repository, a plurality of data sets, each of the data sets comprising at least predicted variables, the predicted variables utilized for generating the analytic model (200); determining the total number of records present in each of the data sets, and determining the columns of the data sets containing only numerical values (202); selecting a column containing only numerical values, from a dataset under consideration (204); counting the number of unique values in the column, and counting the total number of records present in the column (206); comparing the number of unique values in the column and the total number records in the column (208); transforming the column by applying a non-linear transformation to each of the values in the column and generating respective transformed values, in the event that the number of unique values in the column is less than the total records in the column (210); replacing the unique values in each of the columns with the transformed values (212); determining whether there exists a time stamp corresponding to each of the rows in the dataset under consideration, and calculating a plurality of time lags corresponding to each of the rows, the time lags having predetermined orders (214); creating a processed data set, the processed data set comprising a plurality of rows, each row containing columns having the transformed values (216); and creating an analytic model based on at least the processed data set (218).
